Greek counter-terrorist services have detained nine people thought to hold Turkish citizenship in Athens ahead of Turkish President Recep Tayyip Erdoğan’s visit to the country.

Nine persons - eight men and a woman - were being questioned for alleged links to DHKP/C, an outlawed group blamed for a string of attacks in Turkey. The police statement said 'commercial goods, which could potentially be used in making explosive materials' were found.

The detentions come a week ahead of a scheduled visit to Athens by Turkey's President Recep Tayyip Erdoğan.
